MACHINE FOR DRYING YARN.

SPECIFIOATION forming part of Letters men ivofoaaavo, dated July 18, 1899.

Application filed April 5, 1899- Strial No. 711,835. lilo model.)

To all whom it may concern.-

Be it known that I, JOSIAH K. Pnocron,.a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Machines for Drying Yarn and other Materials, of which the following is a specification.

The main object of my invention is to so construct a drying-machine that it can be used for drying yarns or threads either in hanks or skeins suspended from bars or placed loose on a conveyor-belt, and a further object of ,my invention is to prevent the twisting of fine yarn, such as silk'or hemp, during the drying process.

While my invention is especially designed for drying yarns, it can be used for drying any material capable of being suspended or placed loose upon a belt.

In the accompanying drawings, Figure l is a longitudinal sectional View through'a drying-machine made in accordance with my invention. Fig. 2 is a transverse sectional view Fig. 3 is'a viewof a modification. I

A is the drying-compartment, which may be of any width desired. Preferably at one side of this compartment is a circulatingchamber B, in which are contained" pipes or other heating appliance b. In the partition a, between the two compartments A and B, are circulating-fans'C, and above thepartition a is a passage a, so that the heated air will circulate through the two compartments and through the yarn traveling in the compartment A.

D is a perforated endless belt made of any suitable material and supported at each end by belt-wheels d 01, adapted to axles d, one of which may be driven at any speed desired. The belt is supported at intervals by rollers 01 and I preferably run the belt in suitable guides at each side of the machine, as shown in Fig. 2. This belt is situated between the opening a. at the top of the partition on and the fans 0 at the bottom, so that circulation is insured through the belt and the material carried thereby.

E is a second conveyor, mounted, preferably, as shown in the drawings,,the carryingrun of this conveyer being at a given distance above the carrying-run of the belt D. This conveyor consists in the present instance of two chains having sockets e for the yarn-sticks f, and these chains pass around sprocketwheels 6, as shown in Fig. 1. It will be noticed that at the feed end of the machine the upward run of the conveyer E is inclined, so that the sticks with the yarn thereon can be readily placed in the sockets e of the conveyor E. Thus it will be seen that there are two independent conveyer'sD-and E, which pass through the dryingchamber A of the machine. V I

When it is wished to dry fine yarnsor other material that is liable to twist in drying, I mount the yarn on suitable sticks f, and the distance between the traveling runs of the two conveyers is such that the lower ends of the hanks or skeins of yarn will rest upon theperforated conveying-belt D, and I so speed the two belts that their conveying-surfaces the lower portion of the hanks to the belt by adhesion.

A further advantage in a machine of this character is that any material may be placed upon the belt D to be dried, or the material may be hung upon the conveyer E, making a machine which is capable of being converted either into a drier in which the material may need not rest upon the belt D.

The details of construction of the dryingchamber A and the chamber B may be varied according to the use for which the invention is intended, the main feature of the invention being the use of the two con veyers within the one chamber.

I claim as my invention- 1. The combination in a drying-machine,

of the drying-chamber, a perforated endless belt conveyer and a conveyer from which the material to be dried is suspended, the carrying-run of said conveyer being above the carryin g-run of the perforated belt conveyer,substantially as described.

2. The combination in a drying-machine, of the drying-chamber, a perforated endlessbelt conveyer and a conveyer fromwhich the material to be dried is suspended, the carrying-run of said conveyer being above the can rying-run of the perforated belt con veyer and in such position in respect thereto that yarn suspended therefrom will rest upon the perforated belt oonveyer, substantially as and for the purpose described.

In testimony whereof I have signed my' name to this specification in the presence of two subscribing witnesses.

JOSIAH K. PROCTOR.
